Updating Firmware on an ICD-HP

2. The file will be sent in a "zip" format. This may require WinZip, 7Zip or similar utilities to extract the data. Save the file to your desktop, or any other easy to locate file locations.

3. Place the ICD-HP in Flash Mode.

Connect the supplied USB cable to the ICD-HP. The mini-USB connector on ICD-HP is underneath the blue screw down cap on the connector end of the ICD-HP. (This is a standard mini-USB and replacements can be purchased at electronics stores, if necessary.)

Turn the ICD-HP power off with the power button.

Press and hold the ? (Info) button.

Press the power button to turn ICD-HP back on.

Release the ? (Info) button when the display appears. The display will read, “DO NOT DISCONNECT: PLEASE WAIT…” and will show a place for a progress bar.

4. Open the zip file on the computer, and double-click the "Setup.exe" file. This will start a small program in a black window. For instructions on How to Unzip a file with your software follow this Support Article Link.

Note: Do not disconnect the ICD-HP before the update is completed! Doing so may leave the ICD-HP in an unusable state.

If the ICD-HP does become disconnected before the update is complete, start the process over again (step 3) from the beginning.
